SG1543/SG2543/SG3543 POWER SUPPLY OUTPUT SUPERVISORY CIRCUIT DESCRIPTION This monolithic integrated circuit contains all the functions necessary to monitor and control the output of a sophisticated power supply system. Over-voltage (O.V.) sensing with provision to trigger an external SCR “crowbar” shutdown; an under-voltage (U.V.) circuit which can be used to monitor either the output or to sample the input line voltage; and a third op amp/comparator usable for current sensing (C.L.) are all included in this IC, together with an independent, accurate reference generator. Both over and under-voltage sensing circuits can be externally programmed for minimum time duration of fault before triggering.
